Studies of extrasolar planet systems provide additional evidence for fine-tuning in Earth’s planet system. By studying interactions of known and hypothetical bodies in extrasolar planet systems, two U.S. astronomers were able to derive limits on the existence of habitable planets in these systems. The interactions of bodies in the systems cause planetary orbits to become more eccentric (less circular). For hot Jupiter-like planets, the absence of observed eccentricity implies the lack of other planets in the system. Additionally, given the large number of planets in the Earth-Sun system, the low eccentricities of all major planets argues that the system is fine-tuned to ensure Earth remains at a relatively constant distance from the Sun. RTB’s cosmic creation model predicts such fine-tuning as the work of a supernatural Creator preparing a suitable habitat for advanced (particularly human) life.
